OIL-cw. V

To allwhom it may concern:

Be a known' that I, Jews ,P. Grrs, a citizen of the United States, residing at Chicago, in the. county of Cook and State of Illinois, have invented a certain new and useful Improvement in Oil-Cups, of'which the following is a specification.

This invention relates to oil cups for all sorts of machines and particularly to closures for the same. The object'of the invention is to'provide an oil cup, with a spring actuated cover, hinged thereto with 'a minimum number of parts, thus reducing to smallest possible amount the punch or die work to'be done and the consequent expense of the device. The invention consists in means for carrying .out the foregoing ob-;

jects, which can be .easily and cheaply made, which is efiicient and satisfactory in operation and is not readily-liable to get outof.

Fig 2 an end view ofthe mechanism illust'fating this invention in its preferred form. Fig-Bis a central sectional detail view taken in thesame line f Fig. 2. I Fig. 4 is a perspective view of the four -parts constituting the devicofthis inven tion, separated one from the other.

In carrying out this invention, a body membetlO is drawn or punched from sheet metal with an open top end 12 anda contracted bottom discharge nozzle 14 of the usual form. In the operation of forming this body'lO, an elongated metallic hinge inclosing strip 16 is provided,-originally extending straight up upon the side wall of the. cup but ultimately bent down inthe curved form shown to substantially inclose the spring 18 and the pivot pin 20, as shown.

,The cover 22 is stamped out of one piece of metalso as to form a flange 24 extending down and around the upper edge of the cup 10 as clearly shown in the drawing, except -at the portion where the member 16 is located. At this latter point, the cover 22 is elongated into the projecting surface 26 from which depends the ears 28 carrying perforations 30 entered by the pivot pin 20.

position as Fig. 1 on the Specification-0f Letters Patent? 'Patented Aug. 24, 1920. Application nledneceinberw, 1919. Serial "in. 345,024.

One end 32 of the spring18 hooks over the edge of cover portion 26 while the other end 34 of this spring liesbetween the end of member '16 and,the body of cup 10 as clearly appears in Fig. 3, the result being that whenever the cover 22 is rotated in a clockwise direction, as shown in Figs. 1, 2, and 3,

the spring 'isworked against or set so that fwhen the cover is released, the spring throws the cover back to closed position. The spring 18 is always loose enough on pivot 20 to permit this action. The side of member 16, where spring end 32 goes up to engage the cover portion 26, is notched. at 37 so as to provide anopening 39 (Fig. 2) in which the spring lies and moves. The portion of member 16 above notch 37, i. e., between it and the body of cup 10, is the full width of portion 26 of cover 22 between mm 28 so that when theheads of pin 20 are riveted 38'on opposite'sides of inclosing strip 16 so as to more readily insure the cover 22 fitting closely on the upper edge of cup 10, but this detail ofconstruction is not a limitation -upon this invention. These notches provide small. air intakes 40 shown in Fig. 3 which permit the entrance of sufiicient air so that oil can flow down opening 14 while cover 22.

is closed.

From the foregoing, it will be seen that all the manufacturer has to do is to provide the four simple parts shown in Fig. 1, thread the pin or rod 20 through the spring 18 and through the holes 30, then place the inclosing strip 16 of the cup 10 around the spring and below the member 26 and bend it to place, as shown, whereupon the cup of this invention is ready for use in the obvious manner. i

Having thus described my invention" what I claim as new and" desire to secure by Letters Patent, is 2- a 1. In mechanism of the class described, an

end bearing-on the cup, an enveloping strip formed on the side of the cup member, embracing said spring member and pivot to, without unitary connection therewith, so

hold the second end of the spring that, when the cover-is moved off the cup the spring tends to close the cover, for the purposes set forth. p

2. An oil cup including a body having a projecting integral hinge inclosing strip of metal initially extending from. one side thereof, then laterall bent'first outwardly then downwardly to orm a retaining device on the side of the cup for the pivot mechanism of the hinge, a cover over the top of the cup, having ears extending to the sides the body of the cup, so that it will force the cover closed, for the purposes set forth.

3. In mechanism of the class described, an

oil cup chamber, a vcover therefor, a pivot pin having its opposite ends bearing in the cover, a spring about said-pivot having one end bearing on the cup and an enveloping strip formed'on the side of the cup member passing up the side of the cup, over the spring, and thence down around the outside of the spring embracing said spring member and pivotso as to form the only support on the cover for the pivot member and to hold the-second end of the spring so that when the coveris moved off the cup, the spring tends to close the'cover, for the purposes set forth. v V

In witness whereof I have hereunto subscribed my name in the presence of two witness'es.
